Cruise Pitch Attitude...Project Airbus A320

Featured Replies

Hello, I have had the project Airbus A320 for sometime in my FS 2002 aircraft folder. I have the panel from Eric Marciano as well. Thing is I had not really flown it prior yesterday.Last night I decided I would fly it, and while cruising at Mach 0.8 at FL330, I noticed that the airplane was pitched up about 3-4 deg. This is apparent from the PFD, and looking at the airplane in spot view confirms this.My question is: Is this normal for the A320? If the answer is no, is there a parameter I can change in the aircraft.cfg file to correct this? This is for FS2002 Pro.Thanks in advance for any suggestions.

Hi,I own the PSS A320 PRO package and like in real life, the cruise pitch is generally about 2.5 degrees. You need to remember that the aircraft you have may not be exactly matching the real life flight characteristics, and this can not be changed in the aircraft.cfg file, as it is derived from a combination parameters that exist in both the aircraft.cfg and the .air files.Any of what I said above may be wrong, however, and it may be normal under the conditions that you're flying in to have that pitch attitude at cruise. This is only what I believe so please don't treat it as gospel!If you like the A320, I STRONGLY recommend you get the PSS A320 with the upgrade to FS2004. You won't be disappointed!James

Thank You Sir...for you your respone. Ok 2.5 deg in the PSS bird. This means that the Project Airbus one is probably right. yeah maybe one day I will go for the PSS Airbus, if I can develop enough of a liking to the Airbus. I like to fly old airplanes like the 707, 727 and DC-8 where one has to be alert at all times. And maybe, just maybe I will upgrade to FS2004.....or perhaps I will wait for FS2006?? We'll see. Thanks and best regards.

I have no idea what the actual cruse attitude of that aircraft really is under those conditions but 4 deg. sounds like a lot. Think about it, heavy jets are designed to be as economical as possible that means optimizing efficiency during cruise. Strictly from a design point of view the aircraft should be flying in a minimum drag configuration under average cruise conditions and loading. If you're fully loaded for a long transatlantic trip your AOA will be a bit high at first but it should reduce as the plane gets lighter, averaging out around the optimum figure. This does get a bit more complicated then it sounds because you have to consider the incidence angle of the wings, not just the fuselage, but you get the idea. BTW, you can tune this by playing with the cruise lift scalar in the aircraft.cfg file.TonyDigital-Flight

Thanks for the tip Dave. i will visit.

Hello Jimbo,best place is to ask here how to edit the .air file.http://www.avhistory.org/scripts/MegaBBS/f...w.asp?forumid=5I had a look for the info in the archives but they are broken from here so we may need to update the answer. FS9 changed the way it does lift from FS8 so you may need to specify which version you are using.Basically there is a lift coef vs. AoA table and moving the intercept about will change the pitch angle. In FS9 the twist and zero lift angles were disabled and for forward compatibility were supposed to be programmed to zeros in previous versions so the .air files could continue in future. This was secret info and MS told no one we know.Ian
